Genuine Innovations Air Chuck Plus CO2 Inflator



Great-fitting inflator on a range of valves but doesn't really solve the issue of cold hands for the extra money

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Genuine Innovations has tweaked its longstanding AirChuck model to create this AirChuck+ to address those freezing hand issues as the CO2 canister is discharged. The extra fiver over the original, or another tenner above the Ultraflate model, is hard to justify, though.

  • Pros: Quick inflation, 20g canister great for larger tyres
  • Cons: Pricey, head still doesn't keep your hands completely away from the canister

Last month Paul reviewed the standard AirChuck and his only real criticism was that there was no protection from the canister in use. If you haven't used an inflator before you might not be aware of how cold they get when the compressed CO2 gas is released; it's cold enough to burn your skin and even stick. It's not nice.

Unless it is a fully enclosed design like the Ultraflate, most brands supply a little foam sleeve to slip over the gas canister.

What Genuine Innovations has done here instead is to create a new head design, giving your fingers a bit of purchase while pressing it against the valve. It works pretty well, offering a decent amount of area for your fingers to grip.

Even though the spring-loaded head offers an excellent fit around Presta or Schrader valves with little pressure, I still like to use the palm of my hand to keep everything straight and secure. If you aren't wearing mitts, which is most rides for me, your hand still comes into contact with the canister.

This aside, the AirChuck+ works well at getting your tyres inflated, with no gas escaping and a solid feel on the valve.

By altering the amount of force you use to push the head onto the valve you can kind of control the flow, but you need to be quick and dexterous as you can expel the gas fully in a matter of seconds.

The AirChuck+ comes with a single 20g canister which is good for the larger tyres we are seeing on most new bikes these days. One canister will inflate a 28mm 700C tyre to 106psi or a 35mm up to 70psi for instance, and if you are riding 23mm tyres you can inflate both front and rear to 78psi.

There are a lot of inflators on the market at a real range of prices, with the AirChuck+ sitting at the upper end at £29.99. I think it's one of the better ones when it comes to location on the valve, and the overall quality looks to be very good indeed.

Is it worth the extra five quid over the standard AirChuck? I don't know really, when for me it still doesn't solve the freezing hand problem completely. Compared with the Ultraflate at £19.99, the AirChuck+ is lighter and less bulky when in your rear jersey pocket. It isn't by much, though: at 155g including a 20g canister, the Ultraflate is a mere 46g heavier.

A decent attempt at an uprgade over the standard AirChuck but it doesn't quite deliver any real benefit for the extra money. That aside, in operation the AirChuck+ is leak-free and a secure CO2 inflator.

I always use an old ~5 cm length of inner tube as a sleeve around CO2 cartridges. Provides suffficient insulation, and stops them from rattling against other items. This can be reused easily enough at home when swapping a new cartridge into the saddlebag / tool pouch.

To protect your fingers when inflating with a CO2, wrap the old tube a couple of times around the gas cannister. Even if you've gone tubeless you should still have an emergency tube on you.
